case <OC:Enterobacterales> and <FTGroup:3>
FUNCTIONNAD-dependent lysine deacetylase that specifically removes acetyl groups on target proteins. Also acts as a protein-lysine deacylase by mediating protein desuccinylation and de-2- hydroxyisobutyrylation. Modulates the activities of several proteins which are inactive in their acylated form.

FUNCTIONNAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form.
else case <OC:Archaea> and <FTGroup:3>
FUNCTIONNAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form. Deacetylates the N-terminal lysine residue of Alba, the major archaeal chromatin protein and that, in turn, increases Alba's DNA binding affinity, thereby repressing transcription.

FUNCTIONNAD-dependent protein deacetylase which modulates the activities of several proteins which are inactive in their acetylated form.

SUBCELLULAR LOCATIONCytoplasm.
case <FTGroup:3>
DOMAIN2 residues (#{Tyr-64} and #{Arg-67}) present in a large hydrophobic pocket are probably involved in substrate specificity. They are important for desuccinylation activity, but dispensable for deacetylation activity.
end case
SIMILARITYBelongs to the sirtuin family. Class III subfamily.

Comments The gene name sir2 is used in a few prokaryotes. The gene is subject to alternative promoter usage in Salty, giving rise to 2 proteins with different N-termini. The longer protein is used in the seed alignment. Other Enterobacteriaceae probably do that too, maybe other bacteria as well.
